SHOCK-FORMING POSIT FOR CORN-SHOCKERS.

SPECIFICATION forming part of Letters Patent No. 722,397, dated March 10, 1903.

Application. filedMarch 29, 1902. Serial No. 100.591. (No model.)

To all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States, residing at Ohicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Shock-Forming Posts for Corn-Shockers; and I do hereby declare the following to be a full, clear, and exact description of the inv enpresenting the pockets successively in posi-,

tion to receive the stalks from the cutting and forwarding devices, and when all the pockets are full, or at least when enough corn has collected in them to form'a shock, the accumulated stalks are bound into a shock with the post and arms inclosed within it. The bound '2 5 shock is then lifted from the table, carrying the post with it,and is deposited on the ground, standing on end, after which the post is Withdrawn en'dwise from the top of the shock, so as to be again set up on thetable ready to have another shock formed around it.

Theinvention relates exclusively to'the construction of this post and the manner of attaching its arms; and though, as above described, it has been designed with reference to an automatic machine I would have it understood that it is adapted to perform its office of a shock-former whether the corn be delivered to the pockets by hand or machinery and whether the post he used on a machine 40 or elsewhere.

/With this preliminary explanation reference is made to the following description and accompanying drawings for a detailed exposition of the invention.

5 In the drawings, Figure 1 is an elevation of a shock-forming post and a part of the usual crane by which the shock is lifted from the table, this table being also shown in section. Fig. 2 is a plan view of the parts shown in Fig.- 1, the entire table being illustrated. Fig. 3 is an enlarged detail showing the manner of connecting the outreaching arms to the post, these arms being distended. Fig.

4: is a similar view, the arms appearing as folded to the side of the post. Fig. 5 is a section on the line 5 5, Fig. 6; and Fig. 6 is a section on the line 6 6, Fig. 3.

As the invention is not concerned with the arrangement, location, or construction of the table, it will not be described further than to say that the post must be detachable from it and readily restored to place upon it.

The post a is preferably tubular, as shown in Fig. 5, and the connection with the table is most conveniently made by squaring the end of the post and setting it down over a similarly-shaped stud that rises from or projects upward through the table, which is indicated at I).

Theoutreachingarmsareshownatc. There are preferably four of these arms; but obviously there may be any number. They project horizontally at the usual height and may be straight, bent, as shown in the drawings,

or curved, as desired. They are tangential to the circumference of the post and fold close against the side, swinging in vertical planes parallel with but to one side of the post, as

will be described later on. At the point where the arms are to be attached the post is provided with a sleeve d, which is rigidly secured to it by bolt 6, or otherwise. The sleeve has an annular flange f running around its lower part, and on this flange is rotatably supported a collar g, that loosely encircles the upper part of the fixed sleeve 61 and is held down on the flange and prevented from rising by overhanging friction-rollers t',that run on pins or set-screwsj, which are seated in the upper part of the sleeve d, and, as shown in Fig. 5, 0

the post is preferably provided with a number of holes 2 to permit the sleeve to be set higher or lower. The arms 0 are loosely pivoted to ears k,

projecting at diametrically opposite points 5 from the collar g. The ears are constructed as best shown in Figs. 3, 4:, and 5, where it will be seen that they stand oif from the col- 1 lar, so as to allow the arms to be pivoted tangentially to the circumference of the post, as shown in Fig. 5, on radial pivot-pins a. The ears are open at one end, as best shown in Fig. 4, to permit the arms to be extended horizontally, and their rear ends are preferably closed, as shown at k in Fig. 3, so as to prevent the arms from'accidentally getting into the wrong position.

The collar 9 is intended to have only a partial rotation around the post and to be locked thereto by means of a latch l, sliding vertically in a lug m, which projects from the upper edges of the fixed sleeve d. This latch is adapted to drop into a notch n, formed in the upper edge of the collar g, as shownin Figs. 3 and 4, and when so engaged the collar is locked to the post and cannot rotate.

The flange f of the sleeve to is provided at four diametrically opposite points corresponding to the positions of the arms 0 on the sleeve 9 with antifriction rollers 0. These rollers project from the flange in the plane of the arms and form, in connection with the rotatable feature of the collar g, the means for distending and releasing the arms, as will now he more fully described, it being pro-- mised that any other form of stud might be substituted for the roller.

Fig. 3 shows the arms extended horizontally. They are held in this position by the rollers 0 bearing against their under sides when the collar 9 has been moved into the position where the sliding latch drops into the notch '17.. The rollers, as will be understood, always occupy fixed positions, and the arms are elevated by tilting them up on the rollers as fulcrums by giving the sleeve a partial rotation toward the right, as in Fig. 3.

' In Fig. 1 the lower squared end of the shockt'orming post is shown at p in section, and the upper end of the post is connected by a rope q to a hand-winch r on the crane-arm s. This is the usual means for lifting the post and shock vertically from the table and depositing them on the ground, and in order to unlock the latch Z, so as to permit the post to be pulled out of the top of the shock afterit has been thus deposited, there is a second cord 6 running along the crane-arm to a point near the winch.

From the above description it will be fully understood that on releasing the latch the post when pulled upward is free to turn in the collar toward the right in Fig. 3 under the influence of the weight of the outer ends of the arms and the resistance offered by the corn to the passage of the arms upward between the stalks. The arms therefore, in effect, slide down the rollers and fold lengthwise the post against its sides, so as to offer no particular resistance to the withdrawal of the post endwise from the top of the shock by the rope q. After the post has been thus detached from the shock it is restored to place on the shock-receiving table in the manner already described. The collar to which the arms are pivoted is then turned to the right, (see Fig. 3,) thereby causing the arms to ride up on the rollers. The movement of the collar around the post is continued until the latch drops into the notch, which is so positioned that the collar is locked to the post when the arms reach the horizontal position ready toreceive the stalks. The rotation of the collar and post being purely relative, either may be stationary and the actual rotation be performed by the other.

Having thus described my invention, what I claim is 1. A corn-shocker having a table and a detachable shock-forming post having arms connected thereto by radial pivots so as to swing in planes tangential to the circumference of the post, and means for supporting the arms in raised position and allowing them to fold downward alongside of the post.

2. A shock-forming post having swinging arms pivoted to the post at their upper ends, and projecting fulcra for the arms below the pivots, the fulcra and pivots having a movable relation to each other around the post, so as toraise or lower the arms.

3. A shock-forming post having a rotatable collar, arms pivoted at their upper ends to the collar, and rollers projecting from the post below the collar for the arms to fulcrum on when the collar is turned.

4. A shock-forming post having a rotatable collar, arms pivoted at their upper ends to the collar, rollers projecting from the post below the collar for the arms to fulcrum on when the collar isturned, and releasable means for locking the collar in position with the arms raised.

5. A shock-forming post having a rotatable collar 9, a flange f on which the collar rotates, cars is projecting from the collar, arms cpivoted at their upper ends to said ears, and rollers 0 projecting from the flange f in the plane of movement of the arms.

6. A shock-formin g post having'a rotatable collar g, arms 0 pivoted at their upper ends to said collar, rollers o fixed to the post below the collar in the plane of movement of the arms, and a releasable latch for locking the collar in position with the arms raised.

7. A corn-shocker having a table and a detachable shock-formin g post having arms pivoted thereto and swinging in vertical planes parallel with but to one side of the post, and means for supporting said arms in raised position and allowing them to fold downward alongside of the post.

In testimony whereof I affix my signature in presence of two witnesses.
